Call a firm that you saw online and tell them that you were audited for unpaid sales tax on the raw materials that you sold to another retailer. When they try to settle your debt for less or put you on a payment plan, you know that they have no expertise in sales tax litigation! The correct answer is, “no sir, you do not owe any sales tax since this is a business to business transaction. Furthermore, these are considered business inputs and are not taxable.” This knowledge can only be gained overtime by litigating hundreds of sales tax cases.

Client Testimonials


Great lawyer. Dealt with my problems thoroughly and promptly. Went to 2 other lawyers before him and neither understood sales and use tax audits. Experience matters and Mr. Ansari knew exactly how to handle my case and the department of revenue.


True to his word, Attorney Mansoor Ansari relieved me of a tremendous debt to the Internal Revenue Service. At our initial meeting he told me to "place my stress with them and enjoy my summer." Several months later, he informed me that my debt had been reduced to ZERO!! God bless you Attorney Ansari!


Mansoor took my case and updated me every week. He is very quick and very easy to talk to. I felt very comfortable with him and for the first time in a long time I can sleep at night. I don't have any IRS problems and my credit score went up.
